The Valkyrja were originally an early result of the Machines' experiments, to create a revolutionary type of Agent. However, they were considered a failure when they were unable to develop any sympathetic capabilities and were instead aggressive and only thought about their self-preservation. They escaped into the Matrix to become exiles. They are led by one named Valfreyja.
- Named after the Valkyries, female battle maidens in Norse Mythology.
- "Valfreyja" was named by the combination of Valkyrie and the Norse goddess Freyja
